        }
        if (assignments.size() == batch.size()) {
            batch.clear();
        } else {
            batch.removeAll(assignments.values());
        }
        while (batch.size() < SPLIT_BATCH_SIZE && splits.hasNext()) {
            batch.add(splits.next());
        }
        finishingTask.next().finishSplits((int) Math.ceil(MAX_SPLITS_PER_NODE / 50.0));
    }
    return remoteTasks;
}

Example 2 with OperationsPerInvocation

use of org.openjdk.jmh.annotations.OperationsPerInvocation in project presto by prestodb.

public Object bigintGroupByHash(SingleChannelBenchmarkData data) {
    GroupByHash groupByHash = new BigintGroupByHash(0, data.getHashEnabled(), EXPECTED_SIZE);
    data.getPages().forEach(groupByHash::addPage);
    ImmutableList.Builder<Page> pages = ImmutableList.builder();
    PageBuilder pageBuilder = new PageBuilder(groupByHash.getTypes());
    for (int groupId = 0; groupId < groupByHash.getGroupCount(); groupId++) {
        pageBuilder.declarePosition();
        groupByHash.appendValuesTo(groupId, pageBuilder, 0);
